Background technique
Industrial aluminum electrolysis bath is electrolysed using ice crystal-alumina melt as electrolyte by electrode of carbon material,
The metallic aluminium of liquid is precipitated on cathode, the gas based on carbon dioxide is generated on anode.Meanwhile electrolytic cell also give out with
Fluoride, sulfur dioxide, the pernicious gas that dust is major pollutants, spread in potroom, deteriorate working condition, seriously
Influence the health of direct labor.Electrolysis flue gas, which is diffused into around plant area, will pollute atmosphere, development to agriculture-stock production and
People's lives bring great harm.Therefore, under current Environmental Protection Situation, the Treatment process of electrolysis flue gas is further improved,
It is vital for reducing pollutant discharge amount.
Currently, electrolytic cell smoke discharging pipe can satisfy electrolytic cell gas collection in the closed production of electrolytic cell using single tube smoke pipe
Needs.But when electrolytic cell carries out change poles, goes out the grooving operations such as aluminium, exhaust gas volumn is increased considerably, and about electrolytic cell is closed
2~4 times of exhaust gas volumn when production.In the case, if not increasing collection tolerance, it just not can guarantee end electrolytic cell flue gas and do not let out
Dew, and then not can guarantee gas collecting efficiency, greatly increase the uncontrollable discharge of potroom.If according to the exhaust gas volumn of grooving operations
Whole system is designed, then system needs to provide twice of air quantity, increases whole system, needs to carry out whole system complete
Face transformation, directly results in system Construction expense and operating cost increases considerably.Therefore, it is necessary to develop a kind of potroom to have
Double smoke pipe configuration methods of power, uncontrollable discharge when reducing electrolytic cell grooving operations.In electrolytic cell grooving operations, for opening
The electrolytic cell of slot operation increases gas collecting efficiency, and does not influence the flue gas balance to electrolytic cell around.Guaranteeing electrolytic cell gas collection effect
While rate, improvement cost is reduced, it is energy saving, accelerate speed of application, and reduce the influence to original system to the greatest extent.
Summary of the invention
